FigureT-is a section on line 77 of Fig ure 6.

Figure 8 is an elevation of a portion of the cooker on the end oppositeto that shown in Figure 1 and illustrating the tripping means forreleasing the cans to enter the chamber. Referring now more particularlytothe drawing, 1 show at 11 a pair of standards in which is revolublymounted as at 2 a tubular shaft 8 fitted with a head at near one end andengaging a nonrot-ating tube 5. Axially mounted in the shaft 3 to rotatetherewith is a smaller tube 6, this tube also communicating with anon-rotating tube as 7 sothat the parts 3 and'6 may rotate and yetreceive and discharge fluids as hereinafter set forth. The other end ofthe shaft near its standard 1 is also fitted with a head as 8 and acenter tube as 9, and this'shaft and tube are connected to non-rotatintubes as 10 and 11.

Each reference character 12 indicates a tubular chamber mounted upon anannular support 13 which is in turn mounted upon the shaft 3 to rotatetherewith. Each chamber 12 is so positioned upon the support 13 that itsaxis lies in a horizontal plane when in its uppermost position duringthe rotation of support 13 and also when in itslowermost position, butis at the same time angularly positioned relative to the vertical planein which the aXis of the support lies and therefore assumes an angularposition relative to r a horizontal plane when between, the two extremepositions mentioned. from the uppermost to the lowermost positions-thechamber passes through the position of greatest angularity relative to ahorizontal plane as 14;, a suitable angle being selected that willpermit cans to slide easily therethrough.

Near each end of the chamber 12 is formed a recess as 15 and 16 havingvalve seats 17 rected and oppositely acting gate or valvememberspositioned in their respective recesses 1"16'and mounted upon ashaft 23 lying outside of the chamber 12 and parallel therewith andpassing through the housings 19-20. One end of the shaft carries a pin24 at an angle thereto, and the other end has an arm 25 mounted thereoncarrying a terminal pin 26 extending laterally therefrom.

' The valve 21 has a hub portion 27 fitted with In its passage a pin 28which engages a slot 29 in the shaft 23, the said slot being directedtoward the adjacent end oi? the shaft and having a short portion as 30lying at right angles to the axis of the shaft. A spring 31 is insertedbetween the hub 27 and the side of the housing 19 adjacent the end ofthe shaft. The valve has a hub portion 32 fitted with a pin 33 whichengages a slot 3 1-, in the shaft 23, the said slot bcinil. directedtoward the adjacent end of the shaft. A spring 35 is inserted betweenthe hub 32 and the side of the housing 20 adjacent the end oi? theshaft. The result of this eonst ruetion that when the *alves are closedupon seats 17 and i8 and, the shaft 2?) is rotated mantra-clochwise thepins 2S;-l 'l move in the slots and permit the springs to unseat the valves the continued rotation Oil: the shalt turning the valves back intotheir respective housings so that the chaml'ier 12 is clear for thepassage of cans. When the shaft again turned clockwise the pin 28 firstmoves along the edge 30 so that no movement is imparted to valve 21 butthe pin 3?) advances the valve 22 a little ways into the chamber so asto form a stop for the cans admitted to the chamber 12. Further rotationof the shaft carries both of the valves into the chamber to center overtheir respective seats whereupon the slots function to force them intoengagement with the said seats the positions of the pins in the slots inthis last position being indicated at 36 and 37 respectively.

The cooking is effected by means of steam admitted through tube 9.'Communicating with this tube is a conduit 38 comn'nmicating with anannular tube or conduit 39 lying in substantially the plane of theadjacent end of the machine. From this annular conduit the steam is ledto chamber 12 by means of a short tube 41-0 titled with a val ve 4-1 thestem oi which is litted with a cross handle 42. The steam enters one endoi. the chamber at 41-3 and discharged at it through :r'cmuluit 45parallelling the chamber 12 to a poi ut adjacent conduit i-lilwhere itis titled with a valve 4:6 and disclnn'ges into an annular conduit -iiT.The annular conduit 4i? communicates with the hollow shaft 2 by meansoi? a conduit 48. W hen the valves 4;1-i(3 are open and the chamber 12in closed a continuous flow oi steam passes therethrough, but the valvesmay be closed to permit the use of a cooling fluid. Stop pins 49 and 50mounted on stand ard 1 are positioned to engage the cross handle 42 ofvalve 4&1 andat the same time the handle 51 oil. valve 4:6 to open thesame, and other steps are pe. ioned as at 52-53 to close the same. Thesestops are indicated in dotted lines in Figure 1 clearly showing theirpositions relative to the other operating parts hereinafter described.

The cooling under pressure -is effected by means of water admitted intochamber 12 and dischargml therefrom in a manner similar to hat ustdescribed. The Water enters through tube 6 and a conduit 5% to anannular conduit 55 from which it is conducted to each chamber byaconduit 56 titted with a valve 57 having a handle 58. Entering thechamber at 59 it is discharged at 60 through conduit 61 fitted with avalve 62 having a handle 63 and into an annular conduit Get. A conduit65 connects the annular conduit 6% with the discharge tube or shaft 2.Stops 66 and .67 are mounted on standard 1 to engage handles SEE-63 toopen the valves and permit Water to flow through the cham er, and stops6869 are provided as shown to engage the handles and close the valves.By means oi? this arrangement the stops ail-50 first become eii'ectiveto open the steam line for cooking, and subsequently stops 52-53 becomeoperative to close the steam line, followed in'imediateiy by the stopsG66"l' becomin eti'ective to open the water line for cooling and stops6869 for subsequently closing the water line to permit discharge or thetreated cans and the re ception of cans to be coolzec. It is obvious, ofcourse, that the several steps may be inserted at any desired points inthe path of travel of the valve handles to secure the mosteliicientresults in adn'iitting and discharging the cooking andcooiingfluids.

In order to operate the shai't23 and secure the timely opening andclosing of the valves 21-22 in the chan'1ber12, I provide a cam surfaceat 70 so positioned as to engage the pin 26 on arm 25 at the time whenthe chamber is approaching its position of greatest angularity androtate the shaft until the valves are open and the cans discharged. Inorder to accomplish the desired rotation of the assembled chambers Imount an annular rack 71 on one end thereof, and mount a mutilatedpinion 72 in engagement with the rack to drive the same. The teeth at T3rotate the chambers far enough to move the arm 25 to the substantiallyhorizontal position shown in Figure 1 thereby swinging the valve 22 backinto the. housing 20 and permitting the discharge of the cans. hen theteeth 7% again rotate the device a distance the pin 26 engages camsurface 75 and is carried downwardly a. distance thereby partiallyclosing the valve or gate 22 heretofore described. The rotation againstops while the chamber is being filled with cans, the further rotationcarrying the pin 26 over the lower end oi? cam su1'i'ace75 therebycompletely closing the valves 2l22 in the chamber 12 and opening thenext chamber for the discharge of cans thereliron'i.

It now remains to describe the means TFO! introducing the cans into thechamber. For this purpose I provide a tubular magazine 76 having arocker arm 77 mounted on its under side and provided with upturned ends78-79, a spring 8 being inserted between the outer end of the arm andthe magazine as shown,

i 81 and tilt the arm 77. Tilting the arm '1" normally lying in avertical position, is rotated through the positions 82 and 83 to theposition 84 so that it will engage the spring 7 withdraws itsforward'end from the maga zine and allows the cans therein to slide downinto the chamber 12 while its upper end enters the magazine and preventsother cans from sliding in. As the chambers 12 are rotated further andthe shaft 23 rotated to close the valves 21 22 the end pin 24 snaps,oii' oi the spring 81, thereby permitting its forward end. to enter themagazine andiorm a stop for the cans now permitted to slide into themagazine.

The operation of the machine may be summed up as follows, following onechamber from the moment it has been filled and closed. First, the steamis admitted to the chamber for a period of time suhieient to elect thedesired cooking and then shutjoi'l' in the manner described. Then wateris passed through the chamber for any desired period or time and thenshut off as described.

The arm 23 is now actuated by the cam surface thereby completelyopeningthe chamber 12 at both ends and at the same time posi-- tioning the pin24 ready to trip the device holding the cans in the magazine. Thechamher having been at rest long enough to discharge the cans it ismoved forwardly a distance and the arm 23 rotated clockwise a distanceby cam whereby partially closing valve 22 and tripping the arm 77' toempty the magazine 76. Further rotation of the chamber 12 eil'ects thecomplete closure of valves 21-22 by cam 75, and one complete cyclehasbeen completed.

It may now beseen that I have provided a cooker whi-uiein a number ofcans may be.

treated at the same time, the capacity of the machine being determinedby the'length of each chamber 12 and the number of chambers arranged incircular -formation as described, as well as the speed at which themachine is operated.
